Open Access capable FTTH Platform – Protection
First network access DHCP snooping ARP security MAC forced forwarding
Neighboring discovery Dynamic ARP inspection Multiple VLAN registration
User/network protection Separated VLANs Protected against denial of service
attacks Forced uplink
Per virtual subnet/ Provider Without extra commissioning

Open Access capable FTTH Platform – Bandwidth
Fair Bandwidth distribution across all provider sharing FTTH access Avoid concurrency
Wire speed switching Ingress traffic limiter
Assure quality of service Performance Management Class of service tagging and
queuing
Per virtual subnet Without extra commissioning

High investment will lead to sharing models
How to invite simply additional players onto the network?
Open access capable FTTH platform
Master security for multiple providers using the same layer 2 network and FTTH access platform
Provide discrimination free bandwidth distribution
Avoid configuration overhead
Many thanks!
